The lid on the tub latches but will definitely need weight to keep him in, it also has (20) - 1/2" holes drilled and de-burred in the lid for vents. My 4' tank has latching tabs under the observation light to hold the plexi lids closed. Also he doesn't seem stressed out or anything, he's in his hides during the day and active at night, so all this cage talk kinda seems misplaced, the info is appreciated nonetheless
